NUT.

SPBCIFICATION forming part oi' Letters Patent No. 360,621, dated April 5, 1887.

Application filed December 24, 1886. Serial No. 5222468. (No model.)

.To all whom, 't may cancer-m Be it known that I, JOHN C. SHELLITO, of Peun Run, in the connty of Indiana and Stat-e of Pennsylvania, have invented a new and Improved Nut, of which thefollowing is a full, clear, and exact description.

This invention relates to a novel form of nut that is designed more especially for use in connection with hollow axle-skeins, but which may be used in many other ways, the object of the invention being to provide a nut having an increased thread-surface, and consequently one that will not be readily stripped from its axle or bolt.

Reference is to be had to the accompanying drawings, fo'ning a part of this specfication,

in which similar figures of reference indicate corresponding` parts in both the views.

Figure 1 is a View of a portion of an axleskein provided with myinproved form ofnut, and Fig. 2 is a central sectional View of the construction illustrated in Fig. 1.-

In constructing such a nut as the one forming the subject-matter of this application I provide a unt, 10, having a central projection, ll, the peripheral face of which is screwthreaded, as clearly shown at 2 in Fg. 2, the usual internal thread, 3, being forned upon the nut. This projection 11 is arranged to engage with an internally-threaded socket, 12, that is forned in a plug, 13, inserted in the end of the sken 14, the'projecting end of this plug being externallythreaded to engage with the thread3 of thenut 10. The threads 2 and 3 are of the same pitch, so that while the thread forned upon the projection ofthe nutisbrought With such a nut as has been described I obtain more than double the amount of thread: hearing surface, and at the same time greatly stiflen and streugthen the connection between the nut and the aXle,thus overcoming thedanger of stripping` incident to the use of the ordinary single-thread nut.

Although I have described my invention in connection with an axle, it will of course be understood that a nut of the form described could be used in many other ways.

Having th us fully described my invention, I clain as new and desire to secure by Letters Patent- 1. The conbination,with a nut forned with an internal thread, 3, and an externallythreaded projection, 11, of a plug,` or bolt forned with an internally-threaded socket and an extcrnally -threaded project-ieri, substantially as described.

2. The combination,with a nut formed with an internal thread, 3, and an externallythreaded projectiou, 11, of an aX1e-skeinpro- Vided with aplug having a central internallythreaded socket and an externally-threaded projection, substantially as described.
